Old Persons Bike Seat Any Info Appreciated

Hello,
I am new to the site. I just recently purchased a persons bike seat and was looking for any info about it. It is apx 13 inches by 12 & 1/2 inches and has a METAL tag on the back that reads PERSONS LIC. UNDER U.S. PAT. D-204121. The bottom has MADE IN PERSONS U.S.A. a PERSONS PRODUCT and PERMACO 6329. It is in great condition any ideas as to the age or value or any general info is greatly appreciated.
Thanks

Hello,
I decided to sell it on ebay and have already boxed it up for shipping if you look at ebay #320322649566 there are several more pics of it. I was thinking it looked newer to me as well but I have no idea. If you go by the pat. # that dates it as being very old. Thanks for taking the time to respond.
